ASML, one of the world’s leading manufacturers of chip-making lithography equipment for the computer industry, postponed its appearance at a public hearing before the Planning and Zoning Commission Jan. 8, at which company representatives were to apply for a special permit to build more space and parking.

The company is expected to present its case at the next meeting, Jan. 22.

In the meantime, the Planning and Zoning Commission opened the public hearing, as it said it would in public notices, but no one from the public spoke out for or against the proposal.

The company announced in October that strong demand for its Deep Ultraviolet Lithography systems, which are the workhorse of the computer chip lithography industry, and its Extreme Ultraviolet Lithography systems, to print on wafers or even smaller objects, is driving the growth as shipments continue to ramp up in support of customer plans.

The company now employs more than 1,200 in Wilton at 77 Danbury Road. It will add several hundred more employees over the next couple of years, according to general manager Bill Amalfitano, who runs the development and manufacturing center.

ASML will accomodate that employee growth with the requested permission for 45,345 square feet of new building space, and an additional fourth level on its three-decker parking garage previously approved but never built at the facility.

The fourth level of the parking garage will provide 170 new spaces, according to the plan on file at the Planning and Zoning Department.

With the expansion, the total square footage of the development would be 349,059 square feet of floor area.

“The proposed expansion will allow for an increase in the number of employees on site from the current 1,225 to a total of 1,525 employees. The facility operates three shifts. There is no change proposed to the existing site access,” the application on file reads.

The Wilton site is the home of both research and development, which hires engineers, and clean manufacturing, which hires technicians.
